Greg's Tuning Operation uses only the best equipment to ensure that GTO's customers are getting everything they pay for!

On the software side, we use HP Tuners for making the actual computer adjustments.  This powerful but easy to use software simplifies adjustments while still allowing anything required to be adjusted!

On the hardware side, NGK's AFX wideband sensor is now our wideband unit of choice!  This unit is made by the same company that makes the $12,000 units used by GM, Ford, Kenne Bell, and others!  It's accuracy for a portable unit is virtually unmatched!

GTO is currently trying to secure limited dyno time on a local Mustang chassis dynomometer!  This is a high-powered load-bearing dyno that will allow tuning for high horsepower cars!
